As a supermodel and former Victoria's Secret Angel, Helena Christensen is used to people talking about her body. But that doesn't mean she likes it. In fact, she's more sensitive to other women's body-image struggles because of it. The public shaming of one woman, in particular -- reality star and mom-to-be Kim Kardashian -- has the 44-year-old Danish beauty all riled up.

In an open letter posted on Huffington Post, Christensen defends Kardashian against criticism of her weight and slams the recent bullying over her changing body as "sacrilegious." (As reported in the April 1 issue of Us Weekly, the five-months-pregnant 32-year-old has been compared to Shamu and called "huge" and "fat.")

"It is disgusting and despicable the way that certain media constantly harass the pregnant Kim Kardashian," Christensen writes. "It's enough that they persistently project a negative focus on women's physical shapes; but a public bullying and attacking of a pregnant woman because of her growing shape is just lower than low."

The model -- who played Chris Isaak's mesmerizing girlfriend in the 1991 music video "Wicked Game" and is now a successful photographer and clothing designer -- knows firsthand what pregnancy does to a woman's body. She has a 13-year-old son, Mingus Lucien, with ex-boyfriend Norman Reedus (currently starring as Daryl Dixon on "The Walking Dead").

"There should be some moral compass," she continues. "It doesn't matter who the woman is or what she does. No one should ever be publicly judged for their body, but to attack an expecting mother is sacrilegious and just plain wrong. A pregnant woman should not be criticized for her shape, period!!"
